For the following statements about chemical equations, check the boxes that represent true statements. (Select all that apply.) |The identities of chemical compounds can be changed when balancing a chemical equation. When balancing a chemical equation, you can never change the coefficient of any chemical formula. Chemical equations tell us the identities of the reactants and the products. In a chemical equation, the reactants are on the right and the products are on the left. When balancing a chemical equation, you can never change the subscripts of any chemical formula.

Consider a double replacement reaction between Zinc (ll) chloride and sodium hydroxide: ZnCl2+NaOH ==> Complete the chemical equation by: 1. Rewriting it to include electrically-neutral ionic product formulas for each formula. To clarify instead of just writing the product formulas rewrite the entire equation. Concerning the "electrically neutral" part, you are reminded that if for example, Na + Cl2 ==> were your reactants, you would not predict NaCl2 as a chemical product because that is not an electrically neutral compound formula. The Na would have a +1 charge and, the Cl would have a -1 charge, 2 (-1) charges would give an overall -2 charge which would not produce an overall 0 charge. 2. Balance it. 3. Add subscripts (aq, I, s, or g) to show how the reactants combine and which product will precipitate to be collected as a solid. 4. Provide subscripts for both reactants and both products.
Equation Sheet Scientists describe matter using chemical equations. These descriptions identify the types of matter that react and are produced from the reaction, and they can identify the quantities of those materials as well. In this investigation you will explore how these equations are written and used.

Choose a chemical reaction that is used in industry, research, or nature. DO NOT USE the photosynthesis process or the cellular respiration process. Photosynthesis and cellular respiration are not single chemical reactions; they are each a series of chemical reactions. For the reaction that you choose: 1) Write the balanced chemical equation for the reaction (include the phases). 2) What is/are the reactant(s)? 3) What is/are the product(s)? 4) Why is this reaction important in either industry, research, or nature?
Chemicals won’t react unless you have added the right ratios. If you are trying to create a product, you must add the correct amounts of reactants; otherwise it won’t form. When you balance an equation, it will inform you about how much of the reactant you need, which will enable you to guess how much product you will make. You must establish a ratio for the reaction to occur. In your opinion, which one of these reasons is the best? Justify your response. In your opinion, which of these reasons is the worst?

One day in lab, while adding a gnarled root to a dark liquid bubbling in an iron cauldron, your friend Raina (an expert chemist) says this: "Many metals can be produced from their oxide ores by reaction at high temperatures with carbon monoxide. Carbon dioxide is a byproduct." Using Raina's statement, and what you already know about chemistry, predict the products of the following reaction. Be sure your chemical equation is balanced! CoO(s) + CO(g) ->
Write balanced chemical equations for the following reactions. For EACH chemical, write the coefficient in the first box, the chemical in the second box, and the state in the third box. Do not use subscripts or superscripts in your answer: for example, Ca3(PO4)2 would be entered "Ca3(PO4)2".
